Subject: [PATCH] rtl8180: silence "dubious: x | !y" sparse warning
Date: Wed, 21 Jul 2010 16:38:25 -0400 [thread overview]
Message-ID: <1279744705-32389-1-git-send-email-linville@tuxdriver.com> (raw)
CHECK drivers/net/wireless/rtl818x/rtl8180_rtl8225.c
drivers/net/wireless/rtl818x/rtl8180_rtl8225.c:53:33: warning: dubious: x | !y
The existing code is clever and works fine, but it's not worth even a
single line of Sparse warning SPAM...
